What is BS EN 60404-8-1- Magnetically hard materials about?
BS EN 60404-8-1 is a European standard on magnetic materials that specifies minimum values for the principal magnetic properties of, and dimensional tolerances for, technically important magnetically hard materials.
NOTE: this part of IEC 60404 provides values for the densities of the materials and the ranges of their chemical compositions.
NOTE: Some additional physical data and mechanical reference values concerning the magnetic materials are given in Table A.1 for information and comparison purposes.
Who is BS EN 60404-8-1 - Magnetically hard materials for?
BS EN 60404-8-1 on magnetically hard materials is relevant to:
- Magnetic material manufacturers 
- Manufacturers of industrial applications such as transformers, inductors etc 
- Metallurgists 
- Product engineers 
- Electrical engineers 
- Quality testing personnel 
Why should you use BS EN 60404-8-1 - Magnetically hard materials?
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. Permanent magnets have a coercivity relating to the magnetic polarization greater than1 kA/m.
BS EN 60404-8-1 provides you specifications of electromagnet and conditions, classification of magnetically hard materials, chemical composition, densities, designation, testing with the description of tables of standard properties that helps you in the classification of magnetic materials.
As a result, BS EN 60404-8-1 enables you to assess the quality of the materials, identify the right magnetic materials for your specific manufacturing methods and engineering needs.
What’s changed since the last update?
BS EN 60404-8-1:2015 replaces the second edition published in 2001 and amendment 1:2004. This edition constitutes a technical revision.
- Recently developed anisotropic Sm-Fe-N bonded magnets are included
- High energy ferrites with La and Co as substituents are included
